I am reorganizing my sitemaps. I am breaking some large sitemaps into smaller ones, merging some and so on. More importantly I am renaming all the sitemaps (I am assigning meaningful suffixes reflecting site sections). I am also in the process of creating a sitemap index file so that management becomes easier in the long run.
To achieve the above objectives, I am deleting the existing sitemaps from search console and from the root folder of my server. My understanding is that Google will stop crawling old sitemaps. Following that I will be adding the new sitemaps to the server and search console.
Note: My site URLs are not going to change. Just that I am organizing the URLs in separate baskets for better administration. The site I am working on is a reasonably large one with over 10000 indexed URLs.
Should I take any specific precautionary measures before such a sweeping change?
